Lloyd’s Register yesterday at the spacious and well organised basement auditorium at its London Fenchurch Street HQ’s, delivered a seminar on their experience and capabilities of Ship Efficiency Solutions.
After a nice buffet lunch, it was food-for-thought, meticulously delivered by Paul McStay, the lead Environmental Specialist, Marine Consulting division at Lloyd’s Register EMEA Southampton office and Constantinos Zegos, senior CFD specialist at The Technical Investigation Department at the Society’s HQ’s in London.
This was Lloyd’s Register showcase for their Computational Fluid Dynamics that has a long history of serving the industry and the unique capability of correlating to measurements made on ships in service, thus bridging the gap between the modelling world and reality. This work is applicable in three segments of a ship’s life.
Firstly at the design stage otherwise named the Concept Design. Here Lloyd’s Register uses advanced mathematical algorithms combined with sophisticated CFD software. This is applied to a hull shape still at the design stage to achieve a mathematically sound optimal hull shape that meets not only the clients goals of performance but also complies with all the structural constraints set at the outset of the project.
Secondly, Energy Efficiency Design Optimisation (EEDO) was presented. This pertains making relatively small modifications to existing ships with the purpose of improving fuel efficiency. Several such measures were shown, emphasising the fact that these are tailored to the individual ship and respective sailing conditions. They do not constitute off the shelf solutions.
Thirdly, Energy Efficiency operational Optimisation (EEOO) was presented. Here the ship operator is given the option of improving the performance of the ship without the need to alter the ship’s design in any way. One such measure is the Trim Optimisation service whereby the ship is simulated in its full sailing envelope and the trims at which the ship requires the least power are identified. This information is presented to the ship Master in an easy to read format.
Within the above categories Lloyd’s Register presented work in their involvement with several high profile energy saving innovation projects, where their services as independent assessors and advisors were well received by their clients. In these instances Lloyd’s did not only verify the key design features of the technologies but took the analysis a step further thus enhancing the clients confidence in the results. Furthermore the unique pool of knowledge within the organisation was exploited to address secondary issues affecting the implementation of these technologies on their route to market such as regulatory aspects structural constraints as well environmental and H&S aspects. All these added tremendous value to the products and boosted investor confidence in them as well. It is important to point out that the majority of cases presented had been validated at sea trials thus eliminating the uncertainty associated to correlating CFD to in service performance.
Interesting questions where heard and replied and good networking took place amongst most of the attendees. Good to see old friends form the past and in particular compatriots Alex Xenakis from Chandris and Takis Markatos from Lyras Maritime Ltd. A must for this seminar to be repeated!
